BACKGROUND

The mammalian target of rapamycin (mTOR) is a serine-threonine kinase related to the lipid kinases of the phosphoinositide 3-kinase (PI3K) family. mTOR exists in two complexes, mTORC1¹ ² and mTORC2³ ⁴, which are differentially regulated, have distinct substrate specificities, and are differentially sensitive to rapamycin. mTORC1 integrates signals from growth factor receptors with cellular nutritional status and controls the level of cap-dependent mRNA translation by modulating the activity of key translational components such as the cap-binding protein and oncogene eIF4E⁵.

Recently, mTOR signaling has been deciphered in increasing detail. The differing pharmacology of inhibitors of mTOR have been particularly informative. The first reported inhibitor of mTOR, Rapamycin is now understood to be an incomplete inhibitor of mTORC1⁶. Rapamycin, is a selective mTORC1 inhibitor through the binding to the FK506 Rapamycin Binding (FRB) domain of mTOR kinase with the aid of FK506 binding protein 12 (FKBP12). The FRB domain of mTOR is accessible in the mTORC1 complex, but less so in the mTORC2 complex. Interestingly, the potency of inhibitory activities against downstream substrates of mTORC1 by the treatment of Rapamycin is known to be diverse among the mTORC1 substrates. For example, Rapamycin strongly inhibits phosphorylation of S6K and phosphorylation of the downstream ribosomal protein S6 which control ribosomal biogenesis. On the other hand, Rapamycin shows only partial inhibitory activity against phosphorylation of 4E-BP1, a major regulator of eIF4E which controls the initiation of CAP-dependent translation. As a result, more complete inhibitors of mTORC1 signaling are of interest⁷.

Recently, a second class of “ATP-site” inhibitors of mTOR kinase, were reported⁶ ⁸. Such inhibitors have been referred to by several names (Torkinib⁶, Torin⁸, asTORi⁹, and others). This class of mTOR inhibitor will be referred to as asTORi (ATP site TOR inhibitor). The molecules compete with ATP, the substrate for the kinase reaction, in the active site of the mTOR kinase (and are therefore also active site mTOR inhibitors). As a result, these molecules inhibit downstream phosphorylation against a broader range of substrates¹⁰. The asTORi also inhibit mTORC2, which is not inhibited by Rapamycin, since the former do not require the FRB domain to bind and inhibit mTORC2. The compound INK128 (now termed MLN0128) is related to PP242^(6,11) and is in numerous anti-cancer Phase I and Phase II clinical trials. MLN0128 has the effect of blocking 4E-BP1 phosphorylation.

Although asTORi may have the effect of blocking 4E-BP1 phosphorylation, these agents may also inhibit mTORC2, which leads to a block of Akt activation due to phosphorylation of Akt S473. This dual action on 4EBP1-P and Akt-P produces a more broad acting agent. For example a dose limiting toxicity of MLN0128 in clinical trials is Grade ≥3 hyperglycemia¹².

Disclosed herein, inter alia, are mTORC1 inhibitors thereby providing solutions to these and other problems in the art.

DETAILED DESCRIPTION

A. DEFINITIONS

The abbreviations used herein have their conventional meaning within the chemical and biological arts. The chemical structures and formulae set forth herein are constructed according to the standard rules of chemical valency known in the chemical arts.

Where substituent groups are specified by their conventional chemical formulae, written from left to right, they equally encompass the chemically identical substituents that would result from writing the structure from right to left, e.g., —CH₂O— is equivalent to —OCH₂—.

The term “alkyl,” by itself or as part of another substituent, means, unless otherwise stated, a straight (i.e., unbranched) or branched non-cyclic carbon chain (or carbon), or combination thereof, which may be fully saturated, mono- or polyunsaturated and can include di- and multivalent radicals, having the number of carbon atoms designated (i.e., C₁-C₁₀ means one to ten carbons). Examples of saturated hydrocarbon radicals include, but are not limited to, groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, t-butyl, isobutyl, sec-butyl, (cyclohexyl)methyl, homologs and isomers of, for example, n-pentyl, n-hexyl, n-heptyl, n-octyl, and the like. An unsaturated alkyl group is one having one or more double bonds or triple bonds. Examples of unsaturated alkyl groups include, but are not limited to, vinyl, 2-propenyl, crotyl, 2-isopentenyl, 2-(butadienyl), 2,4-pentadienyl, 3-(1,4-pentadienyl), ethynyl, 1- and 3-propynyl, 3-butynyl, and the higher homologs and isomers. An alkoxy is an alkyl attached to the remainder of the molecule via an oxygen linker (—O—). An alkyl moiety may be an alkenyl moiety. An alkyl moiety may be an alkynyl moiety. An alkyl moiety may be fully saturated.

The term “alkylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from an alkyl, as exemplified, but not limited by, —CH₂CH₂CH₂CH₂—. Typically, an alkyl (or alkylene) group will have from 1 to 24 carbon atoms, with those groups having 10 or fewer carbon atoms being preferred in the present invention. A “lower alkyl” or “lower alkylene” is a shorter chain alkyl or alkylene group, generally having eight or fewer carbon atoms. The term “alkenylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from an alkene.

The term “heteroalkyl,” by itself or in combination with another term, means, unless otherwise stated, a stable straight or branched non-cyclic chain, or combinations thereof, including at least one carbon atom and at least one heteroatom selected from the group consisting of O, N, P, Si, and S, and wherein the nitrogen and sulfur atoms may optionally be oxidized, and the nitrogen heteroatom may optionally be quaternized. The heteroatom(s) O, N, P, S, and Si may be placed at any interior position of the heteroalkyl group or at the position at which the alkyl group is attached to the remainder of the molecule. Examples include, but are not limited to: —CH₂—CH₂—O—CH₃, —CH₂—CH₂—NH—CH₃, —CH₂—CH₂—N(CH₃)—CH₃, —CH₂—S—CH₂—CH₃, —CH₂—CH₂, —S(O)—CH₃, —CH₂—CH₂—S(O)₂—CH₃, —CH═CH—O—CH₃, —Si(CH₃)₃, —CH₂—CH═N—OCH₃, —CH═CH—N(CH₃)—CH₃, —O—CH₃, —O—CH₂—CH₃, and —CN. Up to two or three heteroatoms may be consecutive, such as, for example, —CH₂—NH—OCH₃ and —CH₂—O—Si(CH₃)₃. A heteroalkyl moiety may include one heteroatom (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include two optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include three optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include four optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include five optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include up to 8 optionally different heteroatoms (e.g., O, N, S, Si, or P).

Similarly, the term “heteroalkylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from heteroalkyl, as exemplified, but not limited by, —CH₂—CH₂—S—CH₂—CH₂— and —CH₂—S—CH₂—CH₂—NH—CH₂—. For heteroalkylene groups, heteroatoms can also occupy either or both of the chain termini (e.g., alkyleneoxy, alkylenedioxy, alkyleneamino, alkylenediamino, and the like). Still further, for alkylene and heteroalkylene linking groups, no orientation of the linking group is implied by the direction in which the formula of the linking group is written. For example, the formula —C(O)₂R′— represents both —C(O)₂R′— and —R′C(O)₂—. As described above, heteroalkyl groups, as used herein, include those groups that are attached to the remainder of the molecule through a heteroatom, such as —C(O)R′, —C(O)NR′, —NR′R″, —OR′, —SR′, and/or —SO₂R′. Where “heteroalkyl” is recited, followed by recitations of specific heteroalkyl groups, such as —NR′R″ or the like, it will be understood that the terms heteroalkyl and —NR′R″ are not redundant or mutually exclusive. Rather, the specific heteroalkyl groups are recited to add clarity. Thus, the term “heteroalkyl” should not be interpreted herein as excluding specific heteroalkyl groups, such as —NR′R″ or the like.

The terms “cycloalkyl” and “heterocycloalkyl,” by themselves or in combination with other terms, mean, unless otherwise stated, non-aromatic cyclic versions of “alkyl” and “heteroalkyl,” respectively, wherein the carbons making up the ring or rings do not necessarily need to be bonded to a hydrogen due to all carbon valencies participating in bonds with non-hydrogen atoms. Additionally, for heterocycloalkyl, a heteroatom can occupy the position at which the heterocycle is attached to the remainder of the molecule. Examples of cycloalkyl include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, 1-cyclohexenyl, 3-cyclohexenyl, cycloheptyl, 3-hydroxy-cyclobut-3-enyl-1,2, dione, 1H-1,2,4-triazolyl-5(4H)-one, 4H-1,2,4-triazolyl, and the like. Examples of heterocycloalkyl include, but are not limited to, 1-(1,2,5,6-tetrahydropyridyl), 1-piperidinyl, 2-piperidinyl, 3-piperidinyl, 4-morpholinyl, 3-morpholinyl, tetrahydrofuran-2-yl, tetrahydrofuran-3-yl, tetrahydrothien-2-yl, tetrahydrothien-3-yl, 1-piperazinyl, 2-piperazinyl, and the like. A “cycloalkylene” and a “heterocycloalkylene,” alone or as part of another substituent, means a divalent radical derived from a cycloalkyl and heterocycloalkyl, respectively. A heterocycloalkyl moiety may include one ring heteroatom (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include two optionally different ring heteroatoms (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include three optionally different ring heteroatoms (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include four optionally different ring heteroatoms (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include five optionally different ring heteroatoms (e.g., O, N, S, Si, or P). A heterocycloalkyl moiety may include up to 8 optionally different ring heteroatoms (e.g., O, N, S, Si, or P).

The terms “halo” or “halogen,” by themselves or as part of another substituent, mean, unless otherwise stated, a fluorine, chlorine, bromine, or iodine atom. Additionally, terms such as “haloalkyl” are meant to include monohaloalkyl and polyhaloalkyl. For example, the term “halo(C₁-C₄)alkyl” includes, but is not limited to, fluoromethyl, difluoromethyl, trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl, 3-bromopropyl, and the like.

The term “acyl” means, unless otherwise stated, —C(O)R where R is a substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl.

The term “aryl” means, unless otherwise stated, a polyunsaturated, aromatic, hydrocarbon substituent, which can be a single ring or multiple rings (preferably from 1 to 3 rings) that are fused together (i.e., a fused ring aryl) or linked covalently. A fused ring aryl refers to multiple rings fused together wherein at least one of the fused rings is an aryl ring. The term “heteroaryl” refers to aryl groups (or rings) that contain at least one heteroatom such as N, O, or S, wherein the nitrogen and sulfur atoms are optionally oxidized, and the nitrogen atom(s) are optionally quaternized. Thus, the term “heteroaryl” includes fused ring heteroaryl groups (i.e., multiple rings fused together wherein at least one of the fused rings is a heteroaromatic ring). A 5,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 5 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring. Likewise, a 6,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 6 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring. And a 6,5-fused ring heteroarylene refers to two rings fused together, wherein one ring has 6 members and the other ring has 5 members, and wherein at least one ring is a heteroaryl ring. A heteroaryl group can be attached to the remainder of the molecule through a carbon or heteroatom. Non-limiting examples of aryl and heteroaryl groups include phenyl, 1-naphthyl, 2-naphthyl, 4-biphenyl, 1-pyrrolyl, 2-pyrrolyl, 3-pyrrolyl, 3-pyrazolyl, 2-imidazolyl, 4-imidazolyl, pyrazinyl, 2-oxazolyl, 4-oxazolyl, 2-phenyl-4-oxazolyl, 5-oxazolyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 2-thiazolyl, 4-thiazolyl, 5-thiazolyl, 2-furyl, 3-furyl, 2-thienyl, 3-thienyl, 2-pyridyl, 3-pyridyl, 4-pyridyl, 2-pyrimidyl, 4-pyrimidyl, 5-benzothiazolyl, purinyl, 2-b enzimidazolyl, 5-indolyl, 1-isoquinolyl, 5-isoquinolyl, 2-quinoxalinyl, 5-quinoxalinyl, 3-quinolyl, and 6-quinolyl. Substituents for each of the above noted aryl and heteroaryl ring systems are selected from the group of acceptable substituents described below. An “arylene” and a “heteroarylene,” alone or as part of another substituent, mean a divalent radical derived from an aryl and heteroaryl, respectively. Non-limiting examples of aryl and heteroaryl groups include pyridinyl, pyrimidinyl, thiophenyl, thienyl, furanyl, indolyl, benzoxadiazolyl, benzodioxolyl, benzodioxanyl, thianaphthanyl, pyrrolopyridinyl, indazolyl, quinolinyl, quinoxalinyl, pyridopyrazinyl, quinazolinonyl, benzoisoxazolyl, imidazopyridinyl, benzofuranyl, benzothienyl, benzothiophenyl, phenyl, naphthyl, biphenyl, pyrrolyl, pyrazolyl, imidazolyl, pyrazinyl, oxazolyl, isoxazolyl, thiazolyl, furylthienyl, pyridyl, pyrimidyl, benzothiazolyl, purinyl, benzimidazolyl, isoquinolyl, thiadiazolyl, oxadiazolyl, pyrrolyl, diazolyl, triazolyl, tetrazolyl, benzothiadiazolyl, isothiazolyl, pyrazolopyrimidinyl, pyrrolopyrimidinyl, benzotriazolyl, benzoxazolyl, or quinolyl. The examples above may be substituted or unsubstituted and divalent radicals of each heteroaryl example above are non-limiting examples of heteroarylene. A heteroaryl moiety may include one ring heteroatom (e.g., O, N, or S). A heteroaryl moiety may include two optionally different ring heteroatoms (e.g., O, N, or S). A heteroaryl moiety may include three optionally different ring heteroatoms (e.g., O, N, or S). A heteroaryl moiety may include four optionally different ring heteroatoms (e.g., O, N, or S). A heteroaryl moiety may include five optionally different ring heteroatoms (e.g., O, N, or S). An aryl moiety may have a single ring. An aryl moiety may have two optionally different rings. An aryl moiety may have three optionally different rings. An aryl moiety may have four optionally different rings. A heteroaryl moiety may have one ring. A heteroaryl moiety may have two optionally different rings. A heteroaryl moiety may have three optionally different rings. A heteroaryl moiety may have four optionally different rings. A heteroaryl moiety may have five optionally different rings.

A fused ring heterocyloalkyl-aryl is an aryl fused to a heterocycloalkyl. A fused ring heterocycloalkyl-heteroaryl is a heteroaryl fused to a heterocycloalkyl. A fused ring heterocycloalkyl-cycloalkyl is a heterocycloalkyl fused to a cycloalkyl. A fused ring heterocycloalkyl-heterocycloalkyl is a heterocycloalkyl fused to another heterocycloalkyl. Fused ring heterocycloalkyl-aryl, fused ring heterocycloalkyl-heteroaryl, fused ring heterocycloalkyl-cycloalkyl, or fused ring heterocycloalkyl-heterocycloalkyl may each independently be unsubstituted or substituted with one or more of the substitutents described herein.

The term “oxo,” as used herein, means an oxygen that is double bonded to a carbon atom.

The term “alkylsulfonyl,” as used herein, means a moiety having the formula —S(O₂)—R′, where R′ is a substituted or unsubstituted alkyl group as defined above. R′ may have a specified number of carbons (e.g., “C₁-C₄ alkylsulfonyl”).

Each of the above terms (e.g., “alkyl,” “heteroalkyl,”, “cycloalkyl”, “heterocycloalkyl”, “aryl,” and “heteroaryl”) includes both substituted and unsubstituted forms of the indicated radical. Preferred substituents for each type of radical are provided below.

Substituents for the alkyl and heteroalkyl radicals (including those groups often referred to as alkylene, alkenyl, heteroalkylene, heteroalkenyl, alkynyl, cycloalkyl, heterocycloalkyl, cycloalkenyl, and heterocycloalkenyl) can be one or more of a variety of groups selected from, but not limited to, —OR′, ═O, ═NR′, ═N—OR′, —NR′R″, —SR′, -halogen, —SiR′R″R′″, —OC(O)R′, —C(O)R′, —CO₂R′, —CONR′R″, —OC(O)NR′R″, —NR″C(O)R′, —NR′—C(O)NR″R′″, —NR″C(O)₂R′, —NR—C(NR′R″R′″)═NR″″, —NR—C(NR′R″)═NR′″, —S(O)R′, —S(O)₂R′, —S(O)₂NR′R″, —NRSO₂R′, —NR′NR″R′″, —ONR′R″, —NR′C═(O)NR″NR′″R″″, —CN, —NO₂, in a number ranging from zero to (2m′+1), where m′ is the total number of carbon atoms in such radical. R, R′, R′, R′″, and R″″ each preferably independently refer to hydrogen, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl (e.g., aryl substituted with 1-3 halogens), substituted or unsubstituted heteroaryl, substituted or unsubstituted alkyl, alkoxy, or thioalkoxy groups, or arylalkyl groups. When a compound of the invention includes more than one R group, for example, each of the R groups is independently selected as are each R′, R″, R′″, and R″″ group when more than one of these groups is present. When R′ and R″ are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 4-, 5-, 6-, or 7-membered ring. For example, —NR′R″ includes, but is not limited to, 1-pyrrolidinyl and 4-morpholinyl. From the above discussion of substituents, one of skill in the art will understand that the term “alkyl” is meant to include groups including carbon atoms bound to groups other than hydrogen groups, such as haloalkyl (e.g., —CF₃ and —CH₂CF₃) and acyl (e.g., —C(O)CH₃, —C(O)CF₃, —C(O)CH₂OCH₃, and the like).

Similar to the substituents described for the alkyl radical, substituents for the aryl and heteroaryl groups are varied and are selected from, for example: —OR′, —NR′R″, —SR′, -halogen, —SiR′R″R′″, —OC(O)R′, —C(O)R′, —CO₂R′, —CONR′R″, —OC(O) NR′R″, —NR″C(O)R′, —NR′—C(O)NR″R′″, —NR″C(O)₂R′, —NR—C(NR′R″R′″)═NR″″, —NR—C(NR′R″)═N R′″, —S(O)R′, —S(O)₂R′, —S(O)₂NR′R″, —NRSO₂R′, —NR′NR″R′″, —ONR′R″, —NR′C═(O)NR″NR′″R″″, —CN, —NO₂, —R′, —N₃, —CH(Ph)₂, fluoro(C₁-C₄)alkoxy, and fluoro(C₁-C₄)alkyl, in a number ranging from zero to the total number of open valences on the aromatic ring system; and where R′, R″, R′″, and R″″ are preferably independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl. When a compound of the invention includes more than one R group, for example, each of the R groups is independently selected as are each R′, R″, R′″, and R″″ groups when more than one of these groups is present.

Two or more substituents may optionally be joined to form aryl, heteroaryl, cycloalkyl, or heterocycloalkyl groups. Such so-called ring-forming substituents are typically, though not necessarily, found attached to a cyclic base structure. In one embodiment, the ring-forming substituents are attached to adjacent members of the base structure. For example, two ring-forming substituents attached to adjacent members of a cyclic base structure create a fused ring structure. In another embodiment, the ring-forming substituents are attached to a single member of the base structure. For example, two ring-forming substituents attached to a single member of a cyclic base structure create a spirocyclic structure. In yet another embodiment, the ring-forming substituents are attached to non-adjacent members of the base structure.

Two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally form a ring of the formula -T-C(O)—(CRR′)_(q)—U—, wherein T and U are independently —NR—, —O—, —CRR′—, or a single bond, and q is an integer of from 0 to 3. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -A-(CH₂)_(r)—B—, wherein A and B are independently —CRR′—, —O—, —NR—, —S—, —S(O)—, —S(O)₂—, —S(O)₂NR′—, or a single bond, and r is an integer of from 1 to 4.

The term “pharmaceutically acceptable salts” is meant to include salts of the active compounds that are prepared with relatively nontoxic acids or bases, depending on the particular substituents found on the compounds described herein. When compounds of the present invention contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino, or magnesium salt, or a similar salt. When compounds of the present invention contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, methanesulfonic, and the like.

Certain specific compounds of the present invention contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts. Other pharmaceutically acceptable carriers known to those of skill in the art are suitable for the present invention. Salts tend to be more soluble in aqueous or other protonic solvents than are the corresponding free base forms. In other cases, the preparation may be a lyophilized powder in 1 mM-50 mM histidine, 0.1%-2% sucrose, 2%-7% mannitol at a pH range of 4.5 to 5.5, that is combined with buffer prior to use.

Thus, the compounds of the present invention may exist as salts, such as with pharmaceutically acceptable acids. The present invention includes such salts. Examples of such salts include hydrochlorides, hydrobromides, sulfates, methanesulfonates, nitrates, maleates, acetates, citrates, fumarates, tartrates (e.g., (+)-tartrates, (−)-tartrates, or mixtures thereof including racemic mixtures), succinates, benzoates, and salts with amino acids such as glutamic acid. These salts may be prepared by methods known to those skilled in the art.

The neutral forms of the compounds are preferably regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents.

Provided herein are agents (e.g. compounds, drugs, therapeutic agents) that may be in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under select physiological conditions to provide the final agents (e.g. compounds, drugs, therapeutic agents). Additionally, prodrugs can be converted to agents (e.g. compounds, drugs, therapeutic agents) by chemical or biochemical methods in an ex vivo environment. Prodrugs described herein include compounds that readily undergo chemical changes under select physiological conditions to provide agents (e.g. compounds, drugs, therapeutic agents) to a biological system (e.g. in a subject, in a cell, in the extracellular space near a cell).

Certain compounds of the present invention can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms are equivalent to unsolvated forms and are encompassed within the scope of the present invention. Certain compounds of the present invention may exist in multiple crystalline or amorphous forms. In general, all physical forms are equivalent for the uses contemplated by the present invention and are intended to be within the scope of the present invention.

As used herein, the term “salt” refers to acid or base salts of the compounds used in the methods of the present invention. Illustrative examples of acceptable salts are mineral acid (hydrochloric acid, hydrobromic acid, phosphoric acid, and the like) salts, organic acid (acetic acid, propionic acid, glutamic acid, citric acid and the like) salts, quaternary ammonium (methyl iodide, ethyl iodide, and the like) salts.

Certain compounds of the present invention possess asymmetric carbon atoms (optical or chiral centers) or double bonds; the enantiomers, racemates, diastereomers, tautomers, geometric isomers, stereoisometric forms that may be defined, in terms of absolute stereochemistry, as (R)-or (S)- or, as (D)- or (L)- for amino acids, and individual isomers are encompassed within the scope of the present invention. The compounds of the present invention do not include those which are known in art to be too unstable to synthesize and/or isolate. The present invention is meant to include compounds in racemic and optically pure forms. Optically active (R)- and (S)-, or (D)- and (L)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. When the compounds described herein contain olefinic bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers.

As used herein, the term “isomers” refers to compounds having the same number and kind of atoms, and hence the same molecular weight, but differing in respect to the structural arrangement or configuration of the atoms.

The term “tautomer,” as used herein, refers to one of two or more structural isomers which exist in equilibrium and which are readily converted from one isomeric form to another. It will be apparent to one skilled in the art that certain compounds of this invention may exist in tautomeric forms, all such tautomeric forms of the compounds being within the scope of the invention.

Unless otherwise stated, structures depicted herein are also meant to include all stereochemical forms of the structure; i.e., the R and S configurations for each asymmetric center. Therefore, single stereochemical isomers as well as enantiomeric and diastereomeric mixtures of the present compounds are within the scope of the invention.

Unless otherwise stated, structures depicted herein are also meant to include compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by ¹³C- or ¹⁴C-enriched carbon are within the scope of this invention.

The compounds of the present invention may also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the compounds may be radiolabeled with radioactive isotopes, such as for example tritium (³H), iodine-125 (¹²⁵I) or carbon-14 (¹⁴C). All isotopic variations of the compounds of the present invention, whether radioactive or not, are encompassed within the scope of the present invention.

The symbol “

” denotes the point of attachment of a chemical moiety to the remainder of a molecule or chemical formula.

The terms “a” or “an,” as used in herein means one or more. In addition, the phrase “substituted with a[n],” as used herein, means the specified group may be substituted with one or more of any or all of the named substituents. For example, where a group, such as an alkyl or heteroaryl group, is “substituted with an unsubstituted C₁-C₂₀ alkyl, or unsubstituted 2 to 20 membered heteroalkyl,” the group may contain one or more unsubstituted C₁-C₂₀ alkyls, and/or one or more unsubstituted 2 to 20 membered heteroalkyls. Moreover, where a moiety is substituted with an R substituent, the group may be referred to as “R-substituted.” Where a moiety is R-substituted, the moiety is substituted with at least one R substituent and each R substituent is optionally different.

Descriptions of compounds of the present invention are limited by principles of chemical bonding known to those skilled in the art. Accordingly, where a group may be substituted by one or more of a number of sub stituents, such substitutions are selected so as to comply with principles of chemical bonding and to give compounds which are not inherently unstable and/or would be known to one of ordinary skill in the art as likely to be unstable under ambient conditions, such as aqueous, neutral, and several known physiological conditions. For example, a heterocycloalkyl or heteroaryl is attached to the remainder of the molecule via a ring heteroatom in compliance with principles of chemical bonding known to those skilled in the art thereby avoiding inherently unstable compounds.

The terms “treating” or “treatment” refers to any indicia of success in the treatment or amelioration of an injury, disease, pathology or condition, including any objective or subjective parameter such as abatement; remission; diminishing of symptoms or making the injury, pathology or condition more tolerable to the patient; slowing in the rate of degeneration or decline; making the final point of degeneration less debilitating; improving a patient's physical or mental well-being. The treatment or amelioration of symptoms can be based on objective or subjective parameters; including the results of a physical examination, neuropsychiatric exams, and/or a psychiatric evaluation. For example, certain methods herein treat diseases associated with mTORC1 activity. Certain methods described herein may treat diseases associated with mTORC1 activity by inhibiting mTORC1 activity. Certain methods described herein may treat diseases associated with mTORC1 by inhibiting mTORC1 activity to a greater degree than inhibiting mTORC2 activity.

Symptoms of a cardiovascular disease would be known or may be determined by a person of ordinary skill in the art. The term “treating” and conjugations thereof, include prevention of an injury, pathology, condition, or disease.

An “effective amount” is an amount sufficient to accomplish a stated purpose (e.g. achieve the effect for which it is administered, treat a disease, reduce enzyme activity, increase enzyme activity, reduce protein function, reduce one or more symptoms of a disease or condition). An example of an “effective amount” is an amount sufficient to contribute to the treatment, prevention, or reduction of a symptom or symptoms of a disease, which could also be referred to as a “therapeutically effective amount.” A “reduction” of a symptom or symptoms (and grammatical equivalents of this phrase) means decreasing of the severity or frequency of the symptom(s), or elimination of the symptom(s). A “prophylactically effective amount” of a drug or prodrug is an amount of a drug or prodrug that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing or delaying the onset (or reoccurrence) of an injury, disease, pathology or condition, or reducing the likelihood of the onset (or reoccurrence) of an injury, disease, pathology, or condition, or their symptoms. The full prophylactic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a prophylactically effective amount may be administered in one or more administrations. The exact amounts will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (vols. 1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed., Lippincott, Williams & Wilkins).

The term “associated” or “associated with” in the context of a substance or substance activity or function associated with a disease (e.g. cancer, autoimmune disease, inflammatory disease, metabolic disease, neurodegenerative disease, fungal infection, cardiovascular disease, or transplant rejection) means that the disease is caused by (in whole or in part), or a symptom of the disease is caused by (in whole or in part) the substance or substance activity or function. As used herein, what is described as being associated with a disease, if a causative agent, could be a target for treatment of the disease. For example, a disease associated with mTORC1 activity may be treated with an agent (e.g. compound as described herein) effective for decreasing the level of mTORC1 activity.

“Control” or “control experiment” or “standard control” is used in accordance with its plain ordinary meaning and refers to an experiment in which the subjects or reagents of the experiment are treated as in a parallel experiment except for omission of a procedure, reagent, or variable of the experiment. In some instances, the control is used as a standard of comparison in evaluating experimental effects.

“Contacting” is used in accordance with its plain ordinary meaning and refers to the process of allowing at least two distinct species (e.g. chemical compounds including biomolecules, or cells) to become sufficiently proximal to react, interact or physically touch. It should be appreciated, however, that the resulting reaction product can be produced directly from a reaction between the added reagents or from an intermediate from one or more of the added reagents which can be produced in the reaction mixture. The term “contacting” may include allowing two species to react, interact, or physically touch, wherein the two species may be a compound as described herein and a protein or enzyme. In some embodiments contacting includes allowing a compound described herein to interact with a protein or enzyme.

As defined herein, the term “inhibition”, “inhibit”, “inhibiting” and the like in reference to a protein-inhibitor (e.g. antagonist) interaction means negatively affecting (e.g. decreasing) the level of activity or function of the protein relative to the level of activity or function of the protein in the absence of the inhibitor. In some embodiments inhibition refers to reduction of a disease or symptoms of disease. Thus, inhibition may include, at least in part, partially or totally blocking stimulation, decreasing, preventing, or delaying activation, or inactivating, desensitizing, or down-regulating signal transduction or enzymatic activity or the amount of a protein.

As defined herein, the term “activation”, “activate”, “activating” and the like in reference to a protein-activator (e.g. agonist) interaction means positively affecting (e.g. increasing) the activity or function of the protein relative to the activity or function of the protein in the absence of the activator (e.g. compound described herein). Thus, activation may include, at least in part, partially or totally increasing stimulation, increasing or enabling activation, or activating, sensitizing, or up-regulating signal transduction or enzymatic activity or the amount of a protein decreased in a disease.

The term “signaling pathway” as used herein refers to a series of interactions between cellular and optionally extra-cellular components (e.g. proteins, nucleic acids, small molecules, ions, lipids) that conveys a change in one component to one or more other components, which in turn may convey a change to additional components, which is optionally propagated to other signaling pathway components.

The term “aberrant” as used herein refers to different from normal. When used to describe enzymatic activity, aberrant refers to activity that is greater or less than a normal control or the average of normal non-diseased control samples. Aberrant activity may refer to an amount of activity that results in a disease, wherein returning the aberrant activity to a normal or non-disease-associated amount (e.g. by administering a compound or using a method as described herein), results in reduction of the disease or one or more disease symptoms.

The term “amino acid” refers to naturally occurring and synthetic amino acids, as well as amino acid analogs and amino acid mimetics that function in a manner similar to the naturally occurring amino acids. Naturally occurring amino acids are those encoded by the genetic code, as well as those amino acids that are later modified, e.g., hydroxyproline, y-carboxyglutamate, and O-phosphoserine. Amino acid analogs refers to compounds that have the same basic chemical structure as a naturally occurring amino acid, i.e., an a carbon that is bound to a hydrogen, a carboxyl group, an amino group, and an R group, e.g., homoserine, norleucine, methionine sulfoxide, methionine methyl sulfonium. Such analogs have modified R groups (e.g., norleucine) or modified peptide backbones, but retain the same basic chemical structure as a naturally occurring amino acid. Amino acid mimetics refers to chemical compounds that have a structure that is different from the general chemical structure of an amino acid, but that functions in a manner similar to a naturally occurring amino acid. The terms “non-naturally occurring amino acid” and “unnatural amino acid” refer to amino acid analogs, synthetic amino acids, and amino acid mimetics which are not found in nature. Examples of amino acid mimetics and polypeptide mimetics include peptoids, D-peptides, and β-peptides. Amino acids may be modified amino acids (natural or mimetics) including additional moieties, for example function, therapeutic, or detectable moieties. Modified amino acids may be modified in the side chain by the addition of additional moieties.

Amino acids may be referred to herein by either their commonly known three letter symbols or by the one-letter symbols recommended by the IUPAC-IUB Biochemical Nomenclature Commission. Nucleotides, likewise, may be referred to by their commonly accepted single-letter codes.

Twenty amino acids are commonly found in proteins. Those amino acids can be grouped into nine classes or groups based on the chemical properties of their side chains. Substitution of one amino acid residue for another within the same class or group is referred to herein as a “conservative” substitution. Conservative amino acid substitutions can frequently be made in a protein without significantly altering the conformation or function of the protein. Substitution of one amino acid residue for another from a different class or group is referred to herein as a “non-conservative” substitution. In contrast, non-conservative amino acid substitutions tend to modify conformation and function of a protein.

Example of Amino Acid Classification

Small/Aliphatic residues: Gly, Ala, Val, Leu, Ile Cyclic Imino Acid: Pro Hydroxyl-containing Residues: Ser, Thr Acidic Residues: Asp, Glu Amide Residues: Asn, Gln Basic Residues: Lys, Arg Imidazole Residue: His Aromatic Residues: Phe, Tyr, Trp Sulfur-containing Residues: Met, Cys

In some embodiments, the conservative amino acid substitution comprises substituting any of glycine (G), alanine (A), isoleucine (I), valine (V), and leucine (L) for any other of these aliphatic amino acids; serine (S) for threonine (T) and vice versa; aspartic acid (D) for glutamic acid (E) and vice versa; glutamine (Q) for asparagine (N) and vice versa; lysine (K) for arginine (R) and vice versa; phenylalanine (F), tyrosine (Y) and tryptophan (W) for any other of these aromatic amino acids; and methionine (M) for cysteine (C) and vice versa. Other substitutions can also be considered conservative, depending on the environment of the particular amino acid and its role in the three-dimensional structure of the protein. For example, glycine (G) and alanine (A) can frequently be interchangeable, as can alanine (A) and valine (V). Methionine (M), which is relatively hydrophobic, can frequently be interchanged with leucine and isoleucine, and sometimes with valine. Lysine (K) and arginine (R) are frequently interchangeable in locations in which the significant feature of the amino acid residue is its charge and the differing pKs of these two amino acid residues are not significant. Still other changes can be considered “conservative” in particular environments (see, e.g., BIOCHEMISTRY at pp. 13-15, 2nd ed. Lubert Stryer ed. (Stanford University); Henikoff et al., Proc. Nat'l Acad. Sci. USA (1992) 89:10915-10919; Lei et al., J. Biol. Chem. (1995) 270(20):11882-11886).

“Polypeptide,” “peptide,” and “protein” are used herein interchangeably and mean any peptide-linked chain of amino acids, regardless of length or post-translational modification. As noted below, the polypeptides described herein can be, e.g., wild-type proteins, biologically-active fragments of the wild-type proteins, or variants of the wild-type proteins or fragments. Variants, in accordance with the disclosure, can contain amino acid substitutions, deletions, or insertions. The substitutions can be conservative or non-conservative. The terms apply to amino acid polymers in which one or more amino acid residue is an artificial chemical mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers and non-naturally occurring amino acid polymer. When a polypeptide includes amino acid mimetics or modified amino acids, the monomer may be connected through bonds that are different from or derivatives of peptide links.

Following expression, the proteins can be isolated. The term “purified” or “isolated” as applied to any of the proteins described herein refers to a polypeptide that has been separated or purified from components (e.g., proteins or other naturally-occurring biological or organic molecules) which naturally accompany it (e.g., other proteins, lipids, and nucleic acid in a cell expressing the proteins). Typically, a polypeptide is purified when it constitutes at least 60 (e.g., at least 65, 70, 75, 80, 85, 90, 92, 95, 97, or 99) %, by weight, of the total protein in a sample.

An amino acid residue in a protein “corresponds” to a given residue when it occupies the same essential structural position within the protein as the given residue. For example, a selected residue in a selected protein corresponds to a residue when the selected residue occupies the same essential spatial or other structural relationship as a specified residue relative to the rest of the protein.

“Pharmaceutically acceptable excipient” and “pharmaceutically acceptable carrier” refer to a substance that aids the administration of an active agent to and absorption by a subject and can be included in the compositions of the present invention without causing a significant adverse toxicological effect on the patient. Non-limiting examples of pharmaceutically acceptable excipients include water, NaCl, normal saline solutions, lactated Ringer's, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, polyvinyl pyrrolidine, and colors, and the like. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the invention. One of skill in the art will recognize that other pharmaceutical excipients are useful in the present invention.

The term “preparation” is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration.

As used herein, the term “administering” means oral administration, administration as a suppository, topical contact, intravenous, parenteral, intraperitoneal, intramuscular, intralesional, intrathecal, intracranial, intranasal or subcutaneous administration, or the implantation of a slow-release device, e.g., a mini-osmotic pump, to a subject. Administration is by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal). Parenteral administration includes, e.g., intravenous, intramuscular, intra-arteriole, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, etc. By “co-administer” it is meant that a composition described herein is administered at the same time, just prior to, or just after the administration of one or more additional therapies (e.g. anti-cancer agent, anti-autoimmune disease agent, anti-inflammatory disease agent, anti-neurodegenerative disease agent, anti-metabolic disease agent, anti-transplant rejection agent, anti-fungal infection agent, or longevity agent). The compound of the invention can be administered alone or can be coadministered to the patient. Coadministration is meant to include simultaneous or sequential administration of the compound individually or in combination (more than one compound or agent). Thus, the preparations can also be combined, when desired, with other active substances (e.g. to reduce metabolic degradation, to increase degradation of a prodrug and release of the drug, detectable agent). The compositions of the present invention can be delivered by transdermally, by a topical route, formulated as applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, jellies, paints, powders, and aerosols. Oral preparations include tablets, pills, powder, dragees, capsules, liquids, lozenges, cachets, gels, syrups, slurries, suspensions, etc., suitable for ingestion by the patient. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water/propylene glycol solutions. The compositions of the present invention may additionally include components to provide sustained release and/or comfort. Such components include high molecular weight, anionic mucomimetic polymers, gelling polysaccharides and finely-divided drug carrier substrates. These components are discussed in greater detail in U.S. Pat. Nos. 4,911,920; 5,403,841; 5,212,162; and 4,861,760. The entire contents of these patents are incorporated herein by reference in their entirety for all purposes. The compositions of the present invention can also be delivered as microspheres for slow release in the body. For example, microspheres can be administered via intradermal injection of drug-containing microspheres, which slowly release subcutaneously (see Rao, J. Biomater Sci. Polym. Ed. 7:623-645, 1995; as biodegradable and injectable gel formulations (see, e.g., Gao Pharm. Res. 12:857-863, 1995); or, as microspheres for oral administration (see, e.g., Eyles, J. Pharm. Pharmacol. 49:669-674, 1997). In another embodiment, the formulations of the compositions of the present invention can be delivered by the use of liposomes which fuse with the cellular membrane or are endocytosed, i.e., by employing receptor ligands attached to the liposome, that bind to surface membrane protein receptors of the cell resulting in endocytosis. By using liposomes, particularly where the liposome surface carries receptor ligands specific for target cells, or are otherwise preferentially directed to a specific organ, one can focus the delivery of the compositions of the present invention into the target cells in vivo. (See, e.g., Al-Muhammed, J. Microencapsul. 13:293-306, 1996; Chonn, Curr. Opin. Biotechnol. 6:698-708, 1995; Ostro, Am. J. Hosp. Pharm. 46:1576-1587, 1989). The compositions of the present invention can also be delivered as nanoparticles.

Pharmaceutical compositions provided by the present invention include compositions wherein the active ingredient (e.g. compounds described herein, including embodiments or examples) is contained in a therapeutically effective amount, i.e., in an amount effective to achieve its intended purpose. The actual amount effective for a particular application will depend, inter alia, on the condition being treated. When administered in methods to treat a disease, such compositions will contain an amount of active ingredient effective to achieve the desired result, e.g., reducing, eliminating, or slowing the progression of disease symptoms (e.g. symptoms of cancer, autoimmune disease, inflammatory disease, metabolic disease, neurodegenerative disease, fungal infection, or transplant rejection). Determination of a therapeutically effective amount of a compound of the invention is well within the capabilities of those skilled in the art, especially in light of the detailed disclosure herein.

The dosage and frequency (single or multiple doses) administered to a mammal can vary depending upon a variety of factors, for example, whether the mammal suffers from another disease, and its route of administration; size, age, sex, health, body weight, body mass index, and diet of the recipient; nature and extent of symptoms of the disease being treated (e.g. symptoms of cancer or neurodegenerative disease), kind of concurrent treatment, complications from the disease being treated or other health-related problems. Other therapeutic regimens or agents can be used in conjunction with the methods and compounds of Applicants' invention. Adjustment and manipulation of established dosages (e.g., frequency and duration) are well within the ability of those skilled in the art.

For any compound described herein, the therapeutically effective amount can be initially determined from cell culture assays. Target concentrations will be those concentrations of active compound(s) that are capable of achieving the methods described herein, as measured using the methods described herein or known in the art.

As is well known in the art, therapeutically effective amounts for use in humans can also be determined from animal models. For example, a dose for humans can be formulated to achieve a concentration that has been found to be effective in animals. The dosage in humans can be adjusted by monitoring compounds effectiveness and adjusting the dosage upwards or downwards, as described above. Adjusting the dose to achieve maximal efficacy in humans based on the methods described above and other methods is well within the capabilities of the ordinarily skilled artisan.

Dosages may be varied depending upon the requirements of the patient and the compound being employed. The dose administered to a patient, in the context of the present invention should be sufficient to effect a beneficial therapeutic response in the patient over time. The size of the dose also will be determined by the existence, nature, and extent of any adverse side-effects. Determination of the proper dosage for a particular situation is within the skill of the practitioner. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached.

Dosage amounts and intervals can be adjusted individually to provide levels of the administered compound effective for the particular clinical indication being treated. This will provide a therapeutic regimen that is commensurate with the severity of the individual's disease state.

Utilizing the teachings provided herein, an effective prophylactic or therapeutic treatment regimen can be planned that does not cause substantial toxicity and yet is effective to treat the clinical symptoms demonstrated by the particular patient. This planning should involve the careful choice of active compound by considering factors such as compound potency, relative bioavailability, patient body weight, presence and severity of adverse side effects, preferred mode of administration and the toxicity profile of the selected agent.

The compounds described herein can be used in combination with one another, with other active agents known to be useful in treating cancer, autoimmune disease, inflammatory disease, metabolic disease, neurodegenerative disease, fungal infection, or transplant rejection, or with adjunctive agents that may not be effective alone, but may contribute to the efficacy of the active agent. The compounds described herein can be used in combination with other active agents known to be longevity agents or anti-aging agents.

In some embodiments, co-administration includes administering one active agent within 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 20, or 24 hours of a second active agent. Co-administration includes administering two active agents simultaneously, approximately simultaneously (e.g., within about 1, 5, 10, 15, 20, or 30 minutes of each other), or sequentially in any order. In some embodiments, co-administration can be accomplished by co-formulation, i.e., preparing a single pharmaceutical composition including both active agents. In other embodiments, the active agents can be formulated separately. In another embodiment, the active and/or adjunctive agents may be linked or conjugated to one another. In some embodiments, the compounds described herein may be combined with treatments for cancer such as radiation or surgery.

The term “specifically (or significantly or selectively) binds to” when referring to a compound described herein binding to a protein or complex (e.g., mTORC1), refers to a binding reaction which is determinative of the presence of the protein or complex in the presence of a heterogeneous population of proteins and other biologics. Thus, under designated assay conditions, the specified compound binds to a particular protein (mTOR) or complex (e.g., mTORC1) and does not bind in a significant amount to other proteins or complexes present in the sample (e.g., mTORC2).

In another aspect is provided a method of modulating mTORC1 activity in a subject in need thereof, including administering to the subject an effective amount of a compound as described herein, or a pharmaceutically acceptable salt thereof. In embodiments, the method includes inhibiting mTORC1 activity. In embodiments, the method includes inhibiting mTORC1 activity and not inhibiting mTORC2 activity. In embodiments, the method includes inhibiting mTORC1 activity more than inhibiting mTORC2 activity. In embodiments, the method includes inhibiting mTORC1 activity at least 1.1 fold as much as inhibiting mTORC2 activity (e.g., at least 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000, 10000, 20000, 30000, 40000, 50000, 60000, 70000, 80000, 90000, 100000, 100000, 200000, 300000, 400000, 500000, 600000, 700000, 800000, 900000, or 1000000 fold).

In some embodiments, the mTORC1 is in a cell. In some embodiments, the cell is a mammalian cell, such as a human cell. The cell may be isolated in vitro, form part of a tissue in vitro, or may form part of an organism.

Modulating mTORC1 activity includes directly or indirectly modulating one or more functions of mTORC1 and/or one or more downstream effects of mTORC1. In other words, the function or effect of mTORC1 is altered compared to the function or effect of mTORC1 when the modulator (e.g., compound as described herein) is not present.

In embodiments, the mTORC1 modulator (e.g., compound as described herein, including in embodiments) is an mTORC1 inhibitor that decreases one or more of: activation of mTORC1, co-factor binding by mTORC1, co-factor binding by mTOR, and/or phosphorylation of 4EBP1. In embodiments, the mTORC1 modulator (e.g., compound as described herein, including in embodiments) is an mTORC1 inhibitor that decreases phosphorylation of S6 and/or S6K. In another embodiment, an effective amount of mTORC1 inhibitor is an amount sufficient to decrease mTORC1 activity in a cell (e.g., in a subject) to reduce cell proliferation relative to the amount of cell proliferation in the absence of mTORC1 inhibitor. In another embodiment, an effective amount of mTORC1 modulator (e.g., inhibitor) is an amount sufficient to increase cell death (e.g., apoptosis).

In embodiments, the compound reduces activation of eIF4E. In embodiments, the compound inhibits phosphorylation of 4E-BP1. In embodiments, the compound does not reduce phosphorylation of Akt. In embodiments, the compound does not reduce phosphorylation of Akt-473 or a residue corresponding to Akt-473. In embodiments, the compound does not cause hyperglycemia.

In an embodiment, modulating mTORC1 activity includes direct binding of the mTORC1 modulator to mTOR. In another embodiment, modulating mTORC1 activity is accomplished indirectly.

F. Examples

A. Example 1

The action of MLN0128 on TORC2 is not thought to be necessary for its anti-cancer activity. This has been analyzed in a genetically engineered mouse model of Akt-driven lymphomagenesis¹⁰. A non-phosphorylatable mutant of 4E-BP1 which is constitutively able to inhibit eIF4E, blocks Akt-driven lymphomagenesis, suggesting that this single substrate of mTOR is sufficient to support cancer cell growth and survival. In some animals harboring the constitutively active Akt and constitutively active 4E-BP1, some tumors which still express the 4E-BP1 mutant (4EBP1^(M)). Presumably, another pathway has been activated which bypasses the block imposed by 4EBP1^(M). These cells offer a genetic test of the mechanism of action of the asTORi class of inhibitors. If the action of asTORi on cells is mediated by 4E-BP1 phosphorylation, then there should be no effect of the drug when added to the cells which bypass 4EBP1^(M). The asTORi, PP242 has no significant effect in such cells (FIG. 1), confirming that the cell killing effects of asTORi is mediated in large part, if not completely, by phosphorylation of 4E-BP1 which leads to activation of eIF4E¹⁰.

This assessment of the mechanism of action of various mTOR inhibitors suggests that inhibition of 4E-BP1 phosphorylation is essential for potent anti-cancer activity. Furthermore, the inhibition of TORC2, leading to dephosphorylation of Akt-473 is the key contributor to the dose limiting toxicity of hyperglycemia in clinical trials of asTORi such as MLN0128, and is dispensable for tumor cell killing.

An emerging desirable feature of kinase inhibitor drugs is the ability to inhibit kinase activity following drug washout¹⁶. The EGFR/HER2 inhibitor Lapatinib, exhibits slow-off kinetics from EGFR which is thought to be caused by a required conformational change in the kinase to allow drug to be released. Regardless of the mechanism, it is thought that kinase inhibitors with slow off kinetics will be better able to robustly inhibit kinase signaling in a tumor. Rather than requiring high drug levels in the blood stream 24hr/day, such slow off drugs may demonstrate better target coverage than the more common rapidly dissociating kinase inhibitors.

B. Example 2

Design and Generation of a Third Class of mTOR inhibitor—“Rapa-Link”. In the last year, the crystal structure of a portion of mTOR was solved by Pavletich and coworkers¹⁷. This structure, in conjuction with a much earlier structure of Rapamycin bound to the isolated FRB and FKBP proteins¹⁸ provides an opportunity to develop a completely new class of mTOR inhibitors. By utilizing the TORC1 selective nature of Rapamycin, and linking Rapamycin to (in a way that does not disrupt Rapamycin's binding to FKBP12 or the FRB domain of mTOR) an asTORi (e.g., MLN0128) we predicted that a new type of pharmacological agent for targeting mTOR could be developed (FIGS. 2A and 2B). This approach to design of an mTOR inhibitor has never been proposed previously and provides a novel pharmacological means of blocking mTOR signaling. The key aspect of this design is to use Rapamycin to “deliver” an asTORi (e.g., MLN0128) to the active site of mTORC1, effectively blocking both pS6 and 4E-BP1. The second aspect of the design would be that linking Rapamycin to an asTORi (e.g., MLN0128) would result in binding to FKBP12 in cells, and in this large complex of an asTORi (e.g., MLN0128)-Rapa/FKBP12, an asTORi (e.g., MLN0128) would be diminished in its ability to bind to mTORC2 and thus would have reduced effects on Akt S473.

The basis for selective inhibition of mTORC1 by the new Rapamycin-asTORi (e.g., MLN0128) conjugate molecules (Rapa-Link) and their comparison to Rapamycin and asTORi (e.g., MLN0128) is shown in FIGS. 3A and 3B.

C. Example 3

In order to determine the optimal regiochemistry and cross-linker length for tethering Rapamycin to an asTORi (e.g., MLN0128), two independent crystal structures of mTOR (PDB:4JT5)¹⁷ and FRB:FKBP12:Rapamycin (1FAP) ¹⁸ were overlayed, using the common FRB domain contained in both structures (FIG. 4A).

To design the hybrid compound, the tethering positions to Rapamycin was designed in a way to minimize disruption of its binding to the FKBP12 protein and FRB domain of mTOR. Similarly, the linking group to an asTORi (e.g., MLN0128) was designed to avoid disrupting the active site inhibitor binding to catalytic domain of mTOR. Analysis of the Rapamycin cocrystal structure (1FAP)¹⁸ revealed that the hydroxyl group at the C40 position of rapamycin is exposed to solvent region and is oriented toward the active site of mTOR (FIG. 4A). For an asTORi (e.g., MLN0128) a tethering position was selected based on co-crystal structures of mTOR using PP242 as the model ATP site ligand, which is highly related to MLN0128 (FIG. 4A). MLN0128 was selected as the asTORi for this work, because 1) MLN0128 is a clinical candidate which has good mTOR selectivity and possesses sufficient drug-like properties; 2) our structure-activity relationship (SAR) knowledge of pyrazolo[3,4-d]pyrimidine analogs is applicable to rational designs of cross-linkers.

In order to design the proper cross-linker (L), we attempted to convert the distance between Rapamycin and the asTORi into a discrete number of heavy atoms using the modeling program, Molecular Operating Environment (MOE) (2013.0801). We first evaluated methylene cross-linkers, L: (CH₂)_(n), with the length from n=10 to n=40 which tethers rapamycin with a substructure of PP242 (precursor of MLN0128) and determined that the long linker (n≥27) would be preferable (FIG. 4B). According to the results of this computational calculation, we designed the following compounds (M-1071, M-1111, M-3059 and M-1115)-see FIG. 4B for chemical structures.

D. Example 4

Chemical Synthesis. We designed Rapa-Link inhibitors (M-1071, M-1111, M-3059, M-1115, etc.) possessing a drug-like cross-linker (polyethylene glycol based) which would provide a rapid means for coupling the two halves of the molecule (azide/alkyne cyclization). We considered the structural complexity of rapamycin and its cost, and decided to apply a convergent synthetic route (Scheme 1-A). Hence, we synthesized propargyl ethyleneglycol introduced rapamycin (III-A) as a precursor (Scheme 3). For the asTORi (Scheme 2), we prepared two types of compounds (II-c) with an attachment “A”; 1) Type A has an amino group at the terminal position; 2) Type B has a carboxylate at the terminal position. Those terminal functional groups will be used to connect the active site inhibitor to the cross-linker by amide formation reaction. Among various kinds of cross-linkers, we selected the polyethylene glycol (PEG) linker since it is found in a number of pharmaceuticals²⁰. We used azide PEG linkers to connect asTORi (IIc-A) followed by triazole formation reaction with propargyl derivative of Rapamycin (III-A) (Scheme 1-A). By using the key intermediates, we also synthesized a negative control compound (M-1115) which is designed to have linker predicted to be too short to allow optimal dual binding to mTOR (FIG. 4B).

Comparison Between Three Classes of mTOR Inhibitors (Rapamycin-Class I, MLN0128-Class II, and Rapa-Link-Class III). Human colorectal carcinoma cell line HCT-15, human hepatocellular carcinoma cell line SNU-449, human renal cancer cell line 786-O, L6 myoblasts and 3T3-L1 cells were purchased from American Type Culture Collection (ATCC) (Manassas, Va. USA). The cells were grown in appropriate medium (vender recommended) supplemented with 10% heat-inactivated fetal bovine serum (FBS), in tissue culture dishes placed in a humidified incubator maintained at 37° C. in an atmosphere of 5% CO₂ and 95% air.

Cell viability assay. Cells were seeded in a 96-multiwell plate at 3000-4000 cells per well in medium containing FBS and cells were incubated at 37° C. overnight. After 18-20 h, compounds in 10× DMSO solution (n=3) were added to the cells and were incubated for additional 3 days in a humidified incubator in an atmosphere of 5% CO₂ and 95% air. After treatment of Cell Titer-Glo® luminescent cell viability assay reagent (Promega Corporation, Madison, Wis. USA), the luminescence value was recorded using SpectraMax M5 Multi-Mode Microplate Readers (Molecular Devices, LLC, Sunnyvale, Calif. USA). Concentration response curves were generated on GraphPad Prism (GraphPad Software, La Jolla, Calif. USA) by calculating the decrease in luminescence values in compound-treated samples relative to the DMSO controls.

Anti-proliferative effects of compounds were evaluated in human colorectal cancer HCT-15 cells (mutation: KRAS, PIK3CA), human hepatocellular carcinoma SNU-449 (mutation: TP53, CDKN2A), SNU-398 (mutation: CTNNB1), SNU-182 (mutation: TP53) and renal adenocarcinoma 786-O (mutation: VHL, PTEN, TP53, CDKN2A) in 72 h after compound treatment. Rapa-Link inhibitors M-1071 and M-1111 showed potent growth inhibitory activity (Table 9). Stronger anti-proliferative activities [EC₅₀ (nM): M-1071; ++++ (SNU-398), ++++ (SNU-449), ++++ (786-O), ++++ (HCT-15), ++++ (SNU-182), and M-1111; ++++ (SNU-398), ++++ (SNU-449), +++ (786-O), +++ (HCT-15), ++++ (SNU-182)] were observed compared to MLN0128 [EC₅₀ (nM): +++ (SNU-398), +++ (SNU-449), ++ (786-O), ++ (HCT-15), ++ (SNU-182)]. In contrast, a shorter version of RapaLINK M-1115 shows less anti-proliferative activity [EC₅₀ (nM): +++ (SNU-182), +++ (SNU-398), + (HCT-15), + (SNU-449 and 786-O)].

TABLE 9 EC₅₀ (nM) values of Rapa-LINK inhibitors (vs. asTORi) SNU-398 SNU-449 786-O HCT-15 SNU-182 M-1071 ++++ ++++ ++++ ++++ ++++ M-1111 ++++ ++++ +++ +++ ++++ M-1115 +++ + + + +++ MLN0128 +++ +++ ++ ++ ++ (++++ = <10 nM, 10 nM < +++ <50 nM, 50 nM < ++ <100 nM, 100 nM < +)

Table 10 represents %inhibition at 10 μM of Rapa-LINK inhibitors (vs. Rapamycin). Rapa-LINK inhibitors showed more potent inhibition in cellular proliferation compared to Rapamycin

TABLE 10 % inhibition at 10 μM of Rapa-LINK inhibitors (vs. Rapamycin) SNU-398 SNU-449 786-O HCT-15 SNU-182 M-1071 +++ ++ ++ +++ ++ M-1111 +++ ++ +++ +++ ++ M-3059 +++ + n.d. n.d. + Rapamycin ++ + + ++ + (n.d.: not determined, + = ≤25%, 25% < ++ ≤ 50%, 50% < +++ ≤ 100%)

Since the Rapa-Link compound contains two classes of mTOR inhibitor, we wondered if the superior efficacy of M-1071 could be attributed to a “linker independent” synergy of these two agents, as reported by others²¹. We compared the effect of M-1071 with a combination of rapamycin and MLN0128 (FIG. 5B). Even when both Rapamycin and MLN0128 were combined, their efficacy was inferior to M-1071. These results suggest that the enhanced anti-proliferative effect of the Class III mTOR inhibitor, M-1071 is derived from its particular property of being a single “linked” molecule, and not simply a mixture of an asTORi with Rapamycin.

G. Example 7

Cellular Signaling Effects of Class I-II-III mTOR Inhibitors. Cells were seeded in 60 mm cell culture dishes and incubated 1-2 days until 70-90% confluency. Cells were treated with compound solution in DMSO (1000×) and incubated at 37° C. in a 5% CO₂ humidified incubator for a given length of time. Whole cell lysates were prepared using RIPA buffer (R3792) (TEKnova, Hollister, Calif. USA) with a phosphatase inhibitor cocktail tablet PhosStop and a protease inhibitor cocktail tablet cOmplete Mini (Roche Diagnostics GmbH, Mannheim, Germany). Cell lysates (based on a certain amount of protein determined by Pierce BCA Protein Assay Kit (PI-23225) (Thermo Fisher Scientific Inc., Waltham, Mass. USA)) were electrophoresed using a Criterion Tris-HCl gel 4-20% (Bio-Rad Laboratories, Hercules, Calif. USA) and transferred to a nitrocellulose membrane (162-0115) (Bio-Rad Laboratories, Hercules, Calif. USA). After incubation for more than 1 h with a blocking buffer at room temperature, membranes were labeled with primary antibodies by overnight incubation at 4° C., followed by 1 hour incubation with horseradish peroxidase-conjugated (HRP-conjugated) secondary antibodies at room temperature. The following antibodies were used for immunoblot: phospho-Akt (S473) (#9271), phospho-Akt (T308) (#2965), total-Akt (#9272), phospho-S6 (Ser240/Ser244) (#2215L), S6 ribosomal protein (#2217), phospho-4E-BP1 (T37/T46) (#2855), total 4E-BP1 (#9644) (Cell Signaling Technology, Inc., Danvers, Mass. USA), FKBP12 (sc-28814) mouse β-actin (sc-8432) (Santa Cruz Biotechnology, Inc., Dallas, Tex. USA), anti-rabbit IgG conjugated with horseradish peroxidase (HRP) (#7074), and anti-mouse IgG conjugated with HRP (#7076) (Cell Signaling Technology, Inc., Danvers, Mass. USA). Nitrocellulose membranes were exposed with SuperSignal® West Pico Chemiluminescent Substrate or Femto Maximum Sensitivity Substrate (Thermo Fisher Scientific Inc., Waltham, Mass. USA) and signals were recorded on a CL-Xposure film (Thermo Fisher Scientific Inc., Waltham, Mass. USA).

Downstream signaling of mTOR was tested using an immunoblotting method at 3 h after compound treatment. Although the active site inhibitor MLN0128 shows pan-mTORC1/2 downstream inhibition (pS6, p4E-BP1 and pAkt S473) in both HCT-15 and SNU-449 cells (FIG. 7, and FIG. 8A), hybrid inhibitors M-1071 and M-1111 showed stronger inhibition of mTORC1 signaling (pS6 and p4E-BP1) compared to mTORC2 downstream Akt S473 phosphorylation. Interestingly, M-1071 and M-1111 showed complete p4E-BP1 inhibition at drug concentrations in which pAkt S473 is not inhibited. These selective modulations of mTORC1 vs mTORC2 have not been achieved by asTORi. On the other hand, M-1115 with a short cross-linker showed weaker p4E-BP1 inhibition. These structure activity relationships explain that potent anti-proliferative activity is derived from mTORC1 complete inhibition (p4E-BP1 and pS6) and that TORC2 inhibition (pAkt) may not enhance anti-proliferative activity in these cell lines.

Although short-term rapamycin treatment shows selective inhibition of mTORC1, it was reported that prolonged treatment of rapamycin also inhibits mTORC2 in various cells²². We examined time-course effects of a Rapa-Link inhibitor on mTORC1 and mTORC2 signaling in SNU-449 (FIG. 8B). Treatment of MLN0128 blocked phosphorylation of pAkt S473 continuously during 0.33-24 h. Treatment of M-1071 or rapamycin treatment underwent transient feedback activation on Akt S473 at 1 and 3 h, and then a slight inhibition was observed at 24 h. The feedback activation following Rapamycin treatment has been reported by Rosen and colleauges²³. pS6 was consistently inhibited by all inhibitors after 3 h to 24 h. Interestingly, response of p4E-BP1 inhibition was varied among inhibitors. Treatment of MLN0128 completely inhibited p4E-BP1 in early onset (0.33-1 h) and then partial phosphorylation of 4E-BP1 was observed after 3 h to 24 h. This is likely mediated by feedback reactivation of the Akt-mTOR pathway as reported by Rosen and colleagues²⁴. In contrast, M-1071 treatment provided continuous complete inhibition of TORC1 outputs within 3-24 h. Treatment of rapamycin showed moderate inhibitory activity against p4E-BP and the potency slightly increased in time-dependent manner. We conclude that M-1071's continuous and strong cellular activities (such as inhibition of p4E-BP1) might be derived from the ability to bind to both the FRB domain and the ATP site of mTOR.

Pharmacodynamic studies of M1071 in human renal cancer 786-O xenograft tumor in mice. M-1071 was intraperitoneally administered to tumor transplanted mice by using Cremophor EL-ethanol [2/1 w/w], and diluting this 1:5 with 5% w/v glucose in water as a vehicle. Tumor samples were collected at 3 h after drug administration. For the MWF group, M-1071 was administered once daily every other day. At 4 h after the last administration, tumor samples were collected. After the freezing tumor samples, they were homogenized and treated with RIPA buffer containing phosphatase inhibitor and protease inhibitor. The following western blotting analysis were conducted in a similar way to abovementioned method.

In the drug treated groups, dose dependent inhibition against phospho-4E-BP1 was observed (FIG. 9). Phosphorylation of S6 was also inhibited by the treatment of M-1071. On the other hand, inhibition of phospho-S473 of Akt was slight even at highest dosing of 5 mg/kg which demonstrated the complete inhibition of pS6 and p4EBP-1.

I. Example 9

Effect on blood glucose level. M-1071, Rapamycin and MLN0128 were intraperitoneally administered to mice (n=3) by using Cremophor EL-ethanol [2/1 w/w], and diluting this 1:5 with 5% w/v glucose in water as a vehicle. Blood glucose levels (mg/dL) were monitored.

It was reported that Akt inhibition by the treatment with Akt inhibitor results in a transient increase in blood glucose in mice²⁵. Because mTORC2 plays a central role in full activation of Akt via phosphorylation of S473 on Akt, monitoring the blood glucose level is thought to be a good readout for mTORC2 inhibition by an mTOR inhibitor. Compared with the vehicle treatment group which showed a slight increase in blood glucose at 15 min, perhaps due to the injection of glucose containing vehicle, MLN0128 treatment groups (1, 3, 5 mg/kg) showed a transient increase in blood glucose level at 30 min (FIG. 10). In contrast, the M-1071 treatment group (5 mg/kg) showed a significantly smaller increase in blood glucose level at 30 min. Furthermore, M-1071 (1, 3 mg/kg) and Rapamycin treatment groups showed no increase in blood glucose levels.

In combination with the aforementioned in vivo pharmacodynamic study results, these results indicate that M-1071 demonstrates mTORC1 selectivity vs. mTORC2 in a mouse model at efficacious doses of mTORC1 inhibition.

Drug Washout Experiment. SNU-449 cells were treated with 30 nM of compounds for 3 h. The medium was aspirated out and cells were washed with fresh 10% FBS in RPMI1640 medium. Then, cells were incubated with fresh 10% FBS in RPMI1640 medium at 37° C. for described time period.

In contrast to MLN0128 washout in which inhibitory effects rapidly disappeared within 1 h, M-1071 treatment showed sustained inhibitory effects in both p4E-BP1 (at least 2 h) and pS6 (at least 4 h). Based on these results, we assumed that the effects with MLN0128 are concentration-dependent because asTORi competes with high concentration of cellular ATP. In contrast, Rapamycin effects tend to be maintained longer after washout compared to asTORi because Rapamycin is not binding to the catalytic site. By utilizing the allosteric characteristics of Rapamycin, the ATP site inhibitor portion of the Rapa-link compound is most likely to be able to stay in the ATP site and overcomes the competition with high concentration of cellular ATP.

Additional Rapa-LINK compounds. Two additional Rapa-LINK compounds, E1010 and E1035, were synthesized to explore the effects of a weaker binder to the ATP site of mTOR.

The first Rapa-LINK inhibitor, M1071, combined the allosteric inhibitor, rapamycin, with the ASi, MLN-0128. E1035 and E1010 combined rapamycin with the known ASi, PP242, and a PP242 derivative, MeO-PP242, respectively (FIG. 12).

The potency of the ASi mTOR inhibition in the Rapa-LINK compounds order from strongest to weakest as follows: MLN0128 (<1 nM), PP242 (IC50=8 nM Feldman, M. E., et al. (2009). PLoS Biology, 7(2), e38), MeO-PP242 (>10 μM). The strongest ASi, MLN0128, in M1071 leads to a potent mTORC1 inhibition (10-25 nM) (FIG. 13A). In this concentration range, M1071 also inhibits mTORC2. However, E1035, which uses PP242 as the ASi, shows a similar mTORC1 inhibition concentration range (10-25 nM) but requires a higher concentration range for mTORC2 inhibition (partial inhibition at 50 nM) (FIG. 13A). Lastly, the weakest ASi, MeO-PP242, in E1010 leads to inhibition of pS6 (S240/244) but little or no inhibition of P-4EBP1 (FIG. 13B). This pattern of inhibition is similar to rapamycin induced phosphorylation changes with only phosphorylation of S6 after E1010 treatment (FIG. 8A and FIG. 13B). Thus, the specificity of the Rapa-LINK compounds shifts more towards mTORC1 as the ASi potency decreases.

We assessed the effects of mTORC1 inhibition by Rapa-LINK compounds on cell proliferation. E1010 and rapamycin had similar effects on cell proliferation in 786-O cells (FIG. 14A). This agrees with the E1010 rapamycin-like mTOR inhibition profile seen in FIGS. 13A-13B. In measuring cell proliferation effects of the more potent Rapa-Link compounds, E1035 and M1071 both have potent effects on cell proliferation (FIG. 13B). The cell proliferation effects of E1035 and M1071 are quite similar, even though the former exhibits a larger window between TORC1 and TORC2 inhibition. This data supports the view that anti-proliferative effects rely on TORC1 rather than TORC2 inhibition, as discussed above.
